Summary of the Invention
Problems to be Solved by the Invention
[0004] In the seat back having the above-described configuration, there is a gap between the pressure receiving plate and the back board on the side surface. Therefore, there is a risk that foreign matter may enter between the pressure receiving plate and the back board when the seat back is in use.
[0005] One aspect of the present disclosure aims to provide a vehicle seat capable of suppressing the entry of foreign matter between a pressure receiving plate and a back board.
Means for Solving the Problems
[0006] One aspect of the present disclosure is a vehicle seat (1) comprising a seat cushion (2) and a seat back (3). The seat back (3) includes a first side frame (311) and a second side frame (312) arranged apart from each other in the seat width direction, a pressure plate (32) positioned to cover the first side frame (311) and the second side frame (312) from the front of the seat, a backboard (33) positioned to cover the first side frame (311) and the second side frame (312) from the rear of the seat, a pad (34) positioned at least in front of the pressure plate (32), and a seat cover (35) constituting the outermost layer of the seat back (3).
[0007] The pressure plate (32) includes a first side frame (311), a second side frame (312), a front wall (321) that covers at least a portion of the backboard (33) from the front of the seat, a first side wall (322) that extends from the first end of the front wall (321) in the seat width direction toward the rear of the seat and covers at least a portion of the first side frame (311) from the outside in the seat width direction, and a second side wall (323) that extends from the second end of the front wall (321) in the seat width direction toward the rear of the seat and covers at least a portion of the second side frame (312) from the outside in the seat width direction. The rear end of the first side wall (322) and the rear end of the second side wall (323) each overlap the backboard (33) from the outside in the seat width direction.
[0008] With this configuration, the first side wall (322) and the second side wall (323) of the pressure plate (32) overlap with the backboard (33), thereby suppressing the formation of a gap between the pressure plate (32) and the backboard (33). As a result, the entry of foreign matter into the space between the pressure plate (32) and the backboard (33) can be suppressed.
[0009] In one aspect of this disclosure, the pad (34) may have a front portion (341) superimposed on the front wall (321), a first lateral portion (342) superimposed on the first side wall (322), and a second lateral portion (343) superimposed on the second side wall (323). With such a configuration, the pad (34) is positioned not only in front of the pressure plate (32) but also to the side, making it easier to adjust the outer shape of the seat back (3). As a result, the aesthetic appeal of the seat back (3) is enhanced.
[0010] In one aspect of this disclosure, the seat cover (35) may extend in the vertical direction and have a fastener (352) positioned at the corner of the seat back (3) that is closest to the first side wall (322) when viewed from above the seat. With such a configuration, the seat cover (35) can be easily attached while suppressing a decrease in the aesthetic appearance of the seat back (3).
[0011] In one aspect of the present disclosure, the backboard (33) may include a first side frame (311), a second side frame (312), a board body (331) that covers at least a portion of the backboard (33) from the rear of the seat, a first extension portion (332) that extends forward from a first end of the board body (331) in the seat width direction and covers at least a portion of the first side frame (311) from the outside in the seat width direction, and a second extension portion (333) that extends forward from a second end of the board body (331) in the seat width direction and covers at least a portion of the second side frame (312) from the outside in the seat width direction. The rear end of the first side wall (322) may cover the first extension portion (332) from the outside in the seat width direction. The rear end of the second side wall (323) may cover the second extension portion (333) from the outside in the seat width direction. With this configuration, the pressure plate (32) and the backboard (33) can be overlapped in front of the rear end surface of the seat back (3). This enhances the aesthetic appeal of the seat back (3).

The lower portion 345 extends from the lower end of the front portion 341 toward the rear of the sheet and is superimposed on the lower wall 325 of the pressure plate 32 from below.
[0059] <Seat Covers> As shown in Figures 5A and 5B, the seat cover 35 covers the entire pad 34 and the entire backboard 33 from the front-to-back direction and the width direction of the seat. In other words, the seat cover 35 covers the front, back, left, and right sides of the frame composed of the frame 31, pressure plate 32, backboard 33 and pad 34.
[0060] The seat cover 35 has a bag-shaped cover body 351 and a fastener 352 that connects the ends of the cover body 351. The cover body 351 is attached to the pad 34 by a connecting clip 398.
[0061] The fastener 352 extends vertically and is positioned at the corner 3A of the seat back 3, as viewed from above the seat, that is closest to the first side wall 322 (i.e., the left rear corner).
[0062] With the zipper 352 open, the seat cover 35 covers the frame 31, pressure plate 32, and backboard 33 together with the pad 34. Closing the zipper 352 in this state completes the design of the seat back 3.
[0063] <Air conditioning equipment> The air conditioning unit 37 shown in Figure 6 is a well-known device that blows air in front of the seat using a fan. The air conditioning unit 37 is attached to the board body 331 of the backboard 33 from the front of the seat, for example, by bolts or rivets.
[0064] <End of pressure plate> As shown in Figure 7A, the rear end of the first side wall 322 of the pressure plate 32 overlaps the backboard 33 from the outside in the sheet width direction. Specifically, the rear end of the first side wall 322 covers the tip 332A of the first extension 332 of the backboard 33 from the outside in the sheet width direction. It is preferable that the rear end of the first side wall 322 is in contact with the first extension 332.
[0065] The tip 332A of the first extension 332 is bent outward in the seat width direction (i.e., to the left). The tip 332A of the first extension 332 is abutted against the rear end of the first side wall 322. Furthermore, the end face of the rear end of the first side wall 322 is flush with the rear surface of the tip 332A of the first extension 332. This makes it possible to provide a shape that satisfies the criteria for internal protrusions inside the vehicle.
[0066] Furthermore, the first lateral portion 342 of the pad 34 wraps around to the point where the first side wall 322 and the first extension portion 332 meet. Specifically, the first lateral portion 342 covers the end face of the rear end of the first side wall 322 and the tip portion 332A of the first extension portion 332 from the rear of the seat.
[0067] As shown in Figure 7B, the rear end of the second side wall 323 of the pressure plate 32 overlaps the backboard 33 from the outside in the sheet width direction. Specifically, the rear end of the second side wall 323 covers the tip 333A of the second extension 333 of the backboard 33 from the outside in the sheet width direction. It is preferable that the rear end of the second side wall 323 is in contact with the second extension 333.
[0068] The tip 333A of the second extension 333 is bent outward in the sheet width direction (i.e., to the right). The tip 333A of the second extension 333 is abutted against the rear end of the second side wall 323. Also, the end face of the rear end of the second side wall 323 is flush with the rear surface of the tip 333A of the second extension 333.
[0069] Furthermore, the second lateral portion 343 of the pad 34 wraps around to the point where the second side wall 323 and the second extension portion 333 meet. Specifically, the second lateral portion 343 covers the end face of the rear end of the second side wall 323 and the tip portion 333A of the second extension portion 333 from the rear of the seat.
[0070] [1-2. Effects] According to the embodiments described in detail above, the following effects can be obtained. (1a) The first side wall 322 and the second side wall 323 of the pressure plate 32 overlap the backboard 33, thereby suppressing the formation of a gap between the pressure plate 32 and the backboard 33. As a result, the entry of foreign matter between the pressure plate 32 and the backboard 33 can be suppressed.
[0071] (1b) Since the pad 34 has a first lateral portion 342 and a second lateral portion 343, the pad 34 is positioned not only in front of the pressure plate 32 but also to the side, making it easier to adjust the outer shape of the seat back 3. As a result, the aesthetic design of the seat back 3 is enhanced.
[0072] (1c) By providing a fastener 352 at the corner 3A closest to the first side wall 322, the seat cover 35 can be easily attached while suppressing a decrease in the aesthetic appearance of the seat back 3.
[0073] (1d) The pressure plate 32 covers the first extension portion 332 and the second extension portion 333 of the backboard 33, allowing the pressure plate 32 and the backboard 33 to overlap in front of the rear end surface of the seat back 3. This enhances the aesthetic appeal of the seat back 3.
